A KML (Keyhole Markup Language File) is a plaintext file format used to display geographic data in an Earth browser such as Google Earth, Google Maps, and MapQuest. KML files specify various geographic information, including points, lines, images, polygons, and models, along with attributes like descriptions, place marks, and camera angles. This format, which is based on XML (eXtensible Markup Language), allows users to not only visualize but also navigate through locations and structures.
A GeoJSON file is a format for encoding a variety of geographic data structures using JavaScript Object Notation (JSON). It is a widely used open standard format designed for representing simple geographical features, along with their non-spatial attributes. GeoJSON supports various geographical data types such as points, lines, polygons, and multi-part collections of these types. It is commonly used for storing and exchanging spatial data on the web, as well as within various Geographic Information Systems (GIS).
